**Linear Relationships**

**Linear Relationships**

### Linear relationships show a steady increase or decrease between two variables.

### In this case, distance and time have a linear relationship as the distance is 25 times the value of the time.

### For every 1 unit of time it increases, the distance increases by 25 units.

**How to Graph Linear Relationships**

**How to Graph Linear Relationships**

### To graph linear relationships, you need to first set up a T-Chart.

### Then you insert values for “X” and find out the corresponding values for “Y”. In this case when X = -3, then Y = 1 and when X = -2 then Y = 2.

### Once you have values for X and Y, you can use those values as co-ordinates and plot that on the Cartesian Plane.
